Cancer Research UK is appealing for volunteers who have a feel for business to come up with commercial fundraising models in a national competition.
The Open Ventures Challenge, which is being run by CRUK with the National Endowment for Science, Technology and the Arts and venture specialist mo.jo, invites entrepreneurs to develop business ideas that will raise money for the charity in return for at least £10,000 of start-up funding and ongoing support.
The competition was launched last October, and the cash will go to up to five winning ventures that the charity hopes will raise a combined annual total of £10m to support its research.
More than 500 people have been involved in the development of the first 150 ideas entered, and the charity is asking these people to help identify the most popular ideas so it can draw up a shortlist of five.
This will be selected by the end of April and finalists will present their ideas to a judging panel in May. CRUK will announce the winners on 17 July.
